So wait... this means you can remotely steal energy from a black hole? Could this be exploited as a power source?
Obviously wouldn't be possible on human time scales any time soon but the fact that physics permits this is interesting.

Existing satellite slingshot maneuvers steal energy from the thing they slingshot around -- every satellite that slingshots off earth steals a very, very small amount of energy from the earth. The closer you get to the center of Earth's mass, the more energy you can steal. It's just that in Earth's case there's all this "atmosphere" and "lithosphere" garbage preventing you from snuggling up right close to the center.
With a black hole, all that stuff is compressed, so you can get closer and steal some of its kinetic energy. (If I understand the concept correctly.)
